Each of the power connection units comprises one of the connecting device 33 and a section of the connecting wire 352 or the electric wire 342 extended along the respective connecting part, i.e. the connecting arm 14, the supporting arm 22, or the awning arms 13, wherein the first and second connectors 331, 332 are electrically connected to two ends of the connecting wire 352 and extended to the two ends of the connecting part. When connecting two connecting parts mechanically, the first connector 331 of one connecting part, e.g. the supporting arm 22, can be detachably connected with the second connector 332 of adjacent connecting part, e.g. the awning arm 13.

[0056] In other words, as shown in FIG. 1, the electrical connection of the lighting arrangement 30 according to the preferred embodiment of the present invention provides that the illuminating unit 32 and/or the auxiliary electrical apparatus 35 can be detachably connected with each other. For example, the electric cord 342 is cut into predetermined sections wherein the first connector 331 is provided at one end of the section of the electric cord 342 and the second connector 332 is provided at another end thereof in such a manner that the sections of the electric cord 342 is detachably connected together by connecting the second connector 332 with the first connector 331. Therefore, sections of the electric cord 342 can be firstly connected together before or after assembling the awning frame 10 of the outdoor umbrella 1. In other words, the lighting arrangement 30 is pre-installed into the outdoor umbrella 1, so as to easily connect the lighting arrangement 30 at the time while assembling the outdoor umbrella.

[0057] The above construction feature substantially solves a big headache of connecting the electrical cords. Generally, if the outdoor umbrella 1 is assembled first, it is very difficult to penetrate the electrical cords through the connected arms. If we want to install the electrical cord first, the manufacturer must get all connecting parts ready and then penetrate the electrical cord through all the separating parts in specific order before connecting the parts together. It is also very troublesome. However, according to the present invention, different production lines can manufacture different connecting parts, such as the support stem 21, the supporting arm 22, the upper housing 11, the awning arms 13, the connecting arms 14, and the lower housing 12, independently and pre-install a power connection unit A inside each connecting part with the first and second connectors 331, 332 being extended and mounted to two ends of the connecting part respectively. Therefore, the manufacturer does not need to worry about the electrical power supply and simply connects all parts together to form the outdoor umbrella 1. Then, the power supply will be arranged simply by connecting all adjacent first and second connectors 331, 332 which are mounted at two neighboring ends of connecting parts, as shown in FIG. 1. Of course, when the user needs to replace any connecting part, he has no need to replace the entire power supply arrangement. Rather, he may simply reconnect the power connection unit A by connecting the first and second connectors 331, 332 thereof with the neighboring power connection units A.

[0058] In other words, the present invention not only facilitates the user to electrically connect and disconnect the lighting arrangement, but also simplifies the assembling and disassembling of the outdoor umbrella. Moreover, all the wires including the electric cords 342 and the connecting wires 352 are received inside the outdoor umbrella 1 so as to prevent the wires being broken and thus keep the aesthetic appearance of the outdoor umbrella 1.

[0059] As shown in FIG. 8, the lighting arrangement 30 further comprises an auto-switch 36 to automatically switchoff the lighting arrangement 30 when the outdoor umbrella 1 is folded up so as to ensure the electrical circuit is cut when the umbrella is not in use. The auto-switch 36 comprises a resilient element 361 supported in the lower housing 12 and a contacting head 362 outwardly protruded from an inner end of the respective supporting arm 22 and arranged to maintain biasing against the resilient element 361 when the supporting arm 22 is pivotally moved with respect to the lower housing 12 while the awning frame 10 is unfolded, that is the connecting wires 352 inside the supporting arm 22 and the lower housing 12 are electrically connected to provide electricity.

[0060] In addition, the connecting wire 352 is cut into two sections for the resilient element 361 and the contacting head 362 affixed thereto in such a manner that the contacting head 362 biases against resilient element 361 to close the circuit of the lighting arrangement 30, so as to switch on the illuminating units 32 and the auxiliary electrical apparatus 35. In other words, the auto-switch 36 can ensure the lighting arrangement 30 is switched off when the user folds up the outdoor umbrella.

[0061] In order to save space for storage or transportation for the outdoor umbrella 1, the outdoor umbrella 1 can be detached into several parts. For example, the supporting arm 22 can be detached from the support stem 21 and the awning frame 10 can be detached from the supporting arm 22. In other words, most of the movable parts of the outdoor umbrella 1 can be detached from each other such that the outdoor umbrella 1 can be disassembled into a compact unit.

[0062]FIG. 9 illustrates an alternative mode of the electric hub 31′ which comprises two C-shaped hub members 311′, having a positive charge and a negative charge respectively, coaxially disposed in the upper housing 11′ of the awning frame 10′ wherein the first connectors 331′ are spacedly provided on the two hub members 311′ for electrically connecting the second connectors 332′ of the illuminating units 32′.

[0063] Each of the second connectors 332′ has two connecting wires extended from the elongated element 322′ and arranged to securely mounted on the two first connectors 331′ respectively, so as to electrically connect the illuminating units 32′ to the electric hub 31′.

[0064] Accordingly, the electric hub 31′ further contains a plurality of U-shaped positioning grooves 313′ radially provided on the upper housing 11′ for inner ends of the illuminating units 32′ fittedly receiving thereon and a housing cover 314′ for enclosing the upper housing 11′, so as to protect the electric hub 31′ inside the upper housing 11′. It is worth to mention that such arrangement is specifically designed for the outdoor umbrella 1′ that the lighting arrangement 30′ is set up permanently while assembling the awning frame 10′ since the user may not always need to disassemble the outdoor umbrella 1′, so as to ensure the electrical connection of the lighting arrangement 30′.

[0065] Accordingly, if any of the illuminating units 32 is out of order, the user may simply detach the old one by disconnecting the connecting device 33 positioned between the awning arm 13 and the connecting arm 14. Then, the user may install a new illuminating unit 32 to the respectively arm 14 and reconnect the connecting device 33 again for power supply. It is so convenience that the user may change different types of illuminating units 32 to use from time to time.

[0066] As shown in FIG. 10, furthermore, the control device 34 may comprise a three-way switch 345 which has one input electrically connected with the power supply 341 and two outputs electrically connected with the electric hub 31 and the auxiliary electrical apparatus 35 respectively, wherein the three-way switch 345 is adapted for selectively switching on the illuminating units 32 and the auxiliary electrical apparatus 35.

[0067] In view of above, the outdoor umbrella of the present invention provides with power supply arrangement for electrical appliance that can substantially achieve the following features:

[0068] (1) The lighting arrangement comprises sections of power connection units pre-installed into the connecting parts of the outdoor umbrella respectively, so that it not only facilitates the user to electrically connect and disconnect the lighting arrangement, but also simplifies the assembling and disassembling of the outdoor umbrella.

[0069] (2) The folding and unfolding operations of the outdoor umbrella will not be interfered after the lighting arrangement is installed into the outdoor umbrella.

[0070] (3) The lighting arrangement does not require to alter the original structural design of the outdoor umbrella, so as to minimize the manufacturing cost of the outdoor umbrella incorporating with the lighting arrangement.

[0071] (4) The electrical cords and switchable power supply are pre-installed to extend inside the framework of outdoor umbrella, such as the awing arms, connecting arms and supporting arms, so that a user is safe and hassle-free to operate the lighting arrangement.

[0072] (5) No expensive or complicate mechanical structure is required to employ in the present invention in order to achieve the above mentioned advantages.
